this device!

INTRODUCTION
Thank you for purchasing a quality LUNA OPTICS product. With
proper care and maintenance your device will provide many hours
of operation and outstanding reliability. Please read this manual –
it is your key to enjoying this exciting and hi-tech product!
NIGHT VISION
Without getting too technical and confusing, let’s try to understand
how this device works and what it can and cannot do:
1. Your night vision device works on the principle of amplifying
(intensifying) available light. The process is called light
amplification. A special tube inside the device does the job –all
you have to do is to power the device on and the tube starts
amplifying whatever the light is available at the moment –
therefore it is important to understand that this device is not
suitable for daylight operation, since there is already enough
light available during daytime to see without any additional
help. Therefore, the first and most important rule of any
night vision device is –never use it during daylight, or in
any bright light condition, which allows you to see well
with your naked eye!
2. Your night vision device operates with batteries when used
with the night vision module. Unlike a daylight scope, where
you see the image due to light traveling through the glass and/
or the prisms, the night vision device works by projecting the
amplified image onto a screen. While the tube is the crucial
component of any night vision device, the optical parts of the
unit are also very important, as they gather the light into the
tube and bring the projected image to your eye. Since the
image is projected on the screen, just like any TV, it has certain
limited resolution…so please do not expect your night vision
device to provide the same crystal clear image, as you see
through your daylight binoculars –after all, you are using this
device in the dark environment, where normally your vision
would be very limited…oh, and another important point – all
night vision devices have green monochrome image –why
green? Because human eye can distinct most details of the
viewing image when presented in green color…other colors do
not show you everything…
3. Another very important notice –since your night vision device
amplifies available light hundreds or even thousands of times –

please be sure not to turn the unit on during daylight or in a well-
lit room –the image will be way too bright for your comfortable
viewing and it also may permanently burn the tube inside the
unit and will surely void your warranty. Please note that for the
safety of this device it has protective lens cover with special filter
–to test the unit during daytime when you bring your newly
bought unit home, or in the shop before you buy it. Please keep
this lens cover on during daytime –even if the unit is turned off.
In addition to the lens cover, we have equipped this unit with an
automatic gain control, which automatically adjusts the
brightness of the screen for most comfortable viewing and
prevents immediate tube damage during bright light conditions.
This high-tech feature however is not intended to completely
replace your attention and care for not exposing this scope to
daylight or any direct bright light.
RIFLESCOPE SPECIFICS:
1. This device can be adapted to the various hunting rifles for use
during the day with the daylight module, or, with the night module,
at night (where allowed by law) or during the hours of dusk and
dawn where natural light is too low to clearly see the target with the
daylight scope. Please take time to learn your state and local laws
concerning hunting laws and regulations. You may get information
by accessing this site: http://www.huntinfo.org/ or by contacting
your local authorities. Luna Optics cannot be held responsible for
misuse or violation of any state or local laws concerning the
purchase and use of night vision riflescopes.
2. One of the advantages of our riflescope is its ability to withstand the
heavy recoil of most typical “large game” hunting calibers. We
recommend the maximum caliber to be .300 Weatherby magnum
(7.62x70mm) or similar calibers with the maximum bullet initial
power of 6,000 joules or less.
3. The unique construction and design of this set allows you to sight
the scope during daytime with the Daylight Module and then use the
same scope with the Night Vision Module at night without further re-
adjustment. Please note that scope will need periodic re-zeroing
especially after frequent use on calibers .308 and larger.
OPERATION:
Now that we’ve covered some of the basics of the technology behind
the night vision, let’s learn how to operate your new device:

NIGHT VISION MODE:
Your Day/Night vision system comes with three major parts:
Base Night Vision Module Daylight Module
Out of the box the unit comes as base connected with the Night Vision
Module (see image below).
INSTALLING THE
BATTERY:
When using with the
night module, your
night vision unit
operates on one 3V
Lithium battery, also
known as 123type.
To install the battery,
remove the Battery
Compartment Cover
(4). Install the
battery according to
the diagram
indicated on the
compartment. Once the battery is inside, replace the cover.
TURNING THE UNIT ON AND OFF:
Your night vision unit has a simple and convenient Power Switch (3). To
turn the unit ON, first flip the Protective Lens Cover (12) up (ONLY IN
THE DARK!) and rotate the Power Switch (3) one dial to ON position.
Look through the rubber Eyecup –you should see the green glow. Even if
the image is not yet sharp, the unit is operating. To turn the unit OFF, flip
the power switch one dial back to the OFF position. The green glow will
disappear immediately indicating the unit is in OFF mode. Always replace
the protective lens cover (12) after the unit is turned off and no longer is
in use.
FOCUSING THE UNIT:
To obtain the sharp image, you must first rotate the Ocular Focusing
Wheel (7) in either direction, until you notice in which position the image
is at its best. After that, rotate the Distance Focusing Wheel (1) also until
the image is at its best. You may have to repeat the process again, until
the image is sharp and clear. Once the clear image is obtained, you no
longer need to adjust the Ocular Focusing Wheel, just rotate the Distance
Focusing Wheel to adjust the distance to the object you are viewing.
OPTIONAL INFRARED ILLUMINATOR:
Night Vision
Module
connected to
Base

The LDN-ERS36M Night Module features an Image Intensifier Tube of
Generation-2+, which has enough light sensitivity to function outdoors
without the help of the Infrared Illuminator. It may however be
beneficiary to purchase an extended range IR illuminator for long distance
shooting or small game hunting. Infrared Illuminator will provide an
additional beam of light invisible to the naked eye and is especially useful
in very dark conditions allowing you to better identify the target and also
see what is behind the target. Mounting the optional IR illuminator is easy
and takes only seconds, as the scope has a special accessory mount
already built-in the Night Module.
Model LN-EIR-2 extended range LED IR illuminator can be purchased by
contacting your dealer, or e-mailing us at: [email protected] (please
indicate the model number of the unit (LDN-ERS36M)). You may also see
the list of our online retailers by visiting our website at:
www.lunaoptics.com and clicking on “Where to Buy” section.
When using the infrared illuminator it is important to remember that like a
regular flashlight, as the distance increases, the intensity of the infrared
light fades away.
DAYLIGHT MODE:
To attach the Daylight
Module you will first
need to remove the
Night Vision Module
from the Base. To do
that you must loosen
the Night Module
Mounting Key (2) by
rotating it
counterclockwise.
When the key is
completely loose (after
1-2 full circles) grasp
the base with one hand and the Night Vision Module with the other hand
and twist the Night Vision Module clockwise until you see the two white
dots (one on the Base and the other on the Night Vision Module align
together. Now pull the Night Vision Module out of the Base.
Take the Daylight Module and connect it to the base so that two white dots
align together. Now twist the Daylight Module counterclockwise so the red
dot on the Module is aligned with the white dot on the Base. Now turn the
Daylight Module Mounting Key (10) clockwise until it’s tight. The Daylight
Module is now attached and the unit should look as image above.

ADJUSTING THE RETICLE:
Your night vision unit is equipped with a sighting
mark called RETICLE, (MILDOT type) which can be
seen in the field of view. Each dot equals 2 mils.
Please note that the reticle can be illuminated by
rotating the Reticle Illumination Control (6). The
battery required for illuminating the reticle is
CR2032. It is included with the unit. To change
the battery –unscrew the top cap of the Reticle
Illumination Control (6), remove the battery and
replace it with the new one the same way.
The reticle is also equipped with windage (horizontal) and elevation
(vertical) adjustments (5). Horizontal adjustment scale is located on the
side of the scope and the vertical adjustment scale is on the top of the
scope. To adjust the scale wheels, remove the covers by turning them
counterclockwise and rotate the scales click-by-click to the desired
position, looking into the eyepiece.
ZEROING THE SCOPE:
Attach Daylight Module to the Base and attach the scope onto the rifle.
Set the weapon on a solid base, or bipod. Remove the horizontal and
vertical adjustments covers (5). View the position of the reticle through
the rubber eyecup. If the reticle is not in the center of the image, move it
to the center by adjusting (rotating) the scales of horizontal and/or vertical
adjustments (7). Once the reticle is in the center of view, align the
weapon with the target, so that the target is in the middle of the cross
section of the reticle. Make the control shot. Observe the bullet impact on
the target and, if necessary, make additional corrections via horizontal and
vertical adjustment wheels. If necessary, repeat the shots until you can
see the correlation between adjusting the scales and the bullet impact.
Once finished, replace the scale covers and close the protective lens cover.
TROUBLESHOOTING:
1. Unit does not turn on in Night Mode:
a) Please check if the battery is inserted according to the
drawing
b) Please make sure the battery is good
c) You may be turning the unit on in a very dark area with the
lens cover still on the unit
d) You may have turned the unit on in a very well lit area
without the lens cover and the unit has shut off for
protection –immediately turn off the unit and do not turn it
back on until you are in the dark condition.
2. Unable to obtain sharp and clear image:

a) You may need to repeat the process of rotating the ocular
focusing wheel (7) and distance focusing wheel (1) several
times until you get a good feel of it
b) You may be viewing an object that it too close –the
minimum focusing distance is approximately 10m or 33 ft
c) You may have dirty objective or ocular lens –you may clean
them with soft lens cleaning cloth
3. There are black dots (specs) in the field of view:
THIS IS NORMAL –BLACK DOTS ARE MICROSCOPIC
PARTICLES INSIDE THE TUBE AND RESULT FROM THE
TUBE MANUFACTURING PROCESS, WHICH IS NEVER
COMPLETELY SPEC-FREE
IMPORTANT INFORMATION: NEVER:
1. Intentionally turn on the unit without protective lens cover during
daylight or in a well-lit area (when operating in Night Mode)
2. Allow direct projecting light into the objective lens (automobile
headlights, flashlight beams, laser beams) (when operating in
Night Mode)
3. Try to disassemble the unit by yourself or by anyone who is not
our authorized technician. Doing so may result in injury and will
void any warranty claims
4. Leave the battery inside the unit for a long period of time –the
